This 3.04 carat Natural Sapphire presents a richly saturated blue face-up appearance, with GUILD recording the colour grade as Intense Blue and assigning the trade name Cornflower Blue. The blue gathers with notable concentration through the centre while lighter flashes move along the step facets, giving the stone a composed and architectural first impression.

Its clipped-corner octagonal outline and step-cut faceting create the hallmarks associated with an emerald-cut presentation: broad reflective planes, defined facet junctions, and a clear sense of depth through the centre. Rather than a splintered sparkle, the stone displays measured flashes and structured light return. The report also notes the special comment “Vibrant-brilliance,” reinforcing the lively visual character of the cut.

At 3.04 carats and approximately 7.78 × 6.83 × 5.32 mm, this Sapphire offers a strong centre-stone scale for a ring or pendant with clear geometric presence. Its proportions would suit a refined solitaire, a diamond-accented three-stone design, or a tailored halo composition, while the loose gemstone may also be developed through SARATTI’s bespoke jewellery service.

September Birthstone

Sapphire is the traditional birthstone for September and is also associated with the 5th and 45th wedding anniversaries. Its durability and broad natural colour range have made it one of the most established gemstones in fine jewellery. This Cornflower Blue example offers an especially structured look through its emerald-cut style faceting and octagonal outline.

Design Invitation

The crisp geometry and concentrated blue of this Sapphire would pair naturally with platinum or white gold for a clean, defined presentation. Tapered side stones, baguette diamonds, or a restrained halo could complement the clipped-corner outline without obscuring the centre. The gemstone may be acquired loose or developed through SARATTI’s bespoke jewellery service.

Your gemstone is set into the design you choose. Every pairing is reviewed by a specialist before production begins.

Chosen with judgement — looking beyond the certificate to colour, character, proportion and presence.

Why we chose this stone

Cornflower Blue at 3.04-carat.

Consider this emerald if cornflower blue is the quality you want to notice first. At 3.04-carat, the emerald cut outline gives that strength enough space to remain visible once the stone is set.

Before you decide

Questions worth asking.

Is this the exact gemstone I will receive — and can I see more of it?

Yes. The gemstone shown on this page is the individual stone you are considering — not a representative image from a parcel.

We photograph and film the actual stone and do everything possible to show its color, proportions and character faithfully. Even so, gemstones can respond differently to daylight, warm interior light and different screens.

If you are uncertain, we can provide additional photographs or video and, where useful, reshoot the stone under different lighting or from another angle before you decide.

Can I confirm the gemstone is still available before I proceed?

Of course.

Send us the product link or reference and our concierge can confirm availability before you proceed.

For an important purchase, we would rather confirm first than have you make a decision around a stone that has already been spoken for.

How do I know which setting will suit this gemstone?

The builder presents settings intended to work with the gemstone you have selected.

Before production begins, the pairing is reviewed for proportion, security and suitability.

If we believe another setting, proportion or approach would serve the stone better, we will tell you before anything is made. The setting should serve the gemstone — not simply accommodate it.

What happens after I choose my gemstone and setting?

We confirm the important details with you before production begins.

That includes your gemstone, setting, metal, side stones where relevant, size, engraving and any personal details.

Nothing enters production until the final specification has been reviewed and approved.

Will I see the finished piece before it is sent?

Yes.

Once your piece is complete, it is photographed and filmed with your gemstone set into it.

Those images are sent to you before dispatch, so you can see the finished jewel before it leaves SARATTI.

How long will my piece take?

Made-to-order pieces generally require around three to four weeks from final approval to completion.

A loose gemstone purchased on its own can usually be prepared for dispatch much sooner.

If you are working towards a proposal, anniversary, birthday or travel date, tell us before ordering. We will let you know what is realistically possible rather than promise a date we cannot honour.

How will my order be delivered?

Your order is sent by insured courier with tracking and appropriate delivery security.

The route and carrier depend on destination and value.

Where duties or local taxes may apply, our concierge can explain the available delivery options before dispatch.

Can I return a loose gemstone?

A loose gemstone may be returned within fourteen days of delivery provided it remains unworn, unset and unaltered, with its packaging and documentation intact.

Please contact us before sending anything back so the return can be arranged securely.

What happens once the gemstone has been set?

A jewel created around your selected gemstone is made specifically for you.

Once the final specification has been approved and production has begun, the gemstone and materials are committed to your piece.

That is why we take time to confirm the details with you before making begins.

What if I am still unsure?

Then do not rush the decision.

We can help you compare this gemstone with another, look again at color or proportion, send additional imagery, discuss a setting or simply talk through what matters most to you.

The right stone should feel considered — not hurried.

What happens after I receive my piece?

Our relationship does not end at delivery.

SARATTI provides ongoing care for the jewelry we create, including inspection, cleaning and appropriate maintenance support as the piece is worn over time.

If anything ever concerns you, speak with us before attempting repair or alteration elsewhere.
